This is our six-part series on Golang Pros and Cons for using Go in a DevOps development cycle. In this one, we discuss Golang’s runtime, compilation, and maintenance speed (the pros); and lack of generics (the) con).
Delve is a debugger for the Go programming language. The goal of the project is to provide a simple, full featured debugging tool for Go. Delve should be easy to invoke and easy to use.
